   Add an element to a document&#039;s field, as multiple elements of a field are represented as an array.
   Unlike arrayAppend(), arrayInsert() allows you to specify where the new element is inserted by
   defining which item it is after, whereas arrayAppend() always appends the new element at the end of the array.
